wow,, i cant believe that just happen, finally today ends the days of days searching for a possible fix. i have an imac with 500 gb .. . i delete all my movies/photos/aplications software .. i left the most important application to me. but either way i always get the disturbance message from my imac saying " your hard drive is almost full, delete things " ... i begin to read a couple of threads about that in this forum.. some1 point me to download a program called omnidisksweepper .. i download the program and I FOUND THE MAIN REASON WHY I DONT HAVE ENOUGH HARDDRIVE .. is because a program called iantivirus, i dont know why but that program is creating files?or something with protection on my imac.. look the photos below... *i want you to tell me your recommendation? * was the best and faster way to delete this entire iantivirus program?. via trash? via security trash or other?via the omnidikssweeper himself ? ..... i think if i trash this in security mode 427.1 gb that going to be days to delete it! please send me your feeds backs... Thanks in advance!
